GAS-CLEANING APPARATUS.

Application filed September 30,

To all whom it may concem:

Be it known that I, JOHN WELLS, a subject of the King of Great Britain, of 36 Sharia Falaki, in the city of Cairo, Egypt, have invented new and useful Improvements in Gas-Cleaning Apparatus, of which the following is a specification.

This invention relates to improvements in gas cleaning apparatus and comprises one or more centrifugal tar extractors constructed in such a manner that the number of tar extractor units can be readily increased or reduced. In combination with the tar extractor units there may be provided a gas booster or delivery fan.

In the accompanying drawing gigure 1 is a longitudinal central section, an

Fig. 2 an end elevation of a gas cleaning apparatus constructed according to this in vention.

As shown in this drawing,

A is a cast iron standard, with four bolt bosses B. The face of A at C is circular in form with an annular groove or depression In the center of the standard A is a lon bearing E attached to the standard A by %0lts F and F, being made detachable so as to be easily replaced. Through the bearing E there runs a shaft G, to which are attached the booster fan H and the tar extraction paddles I. On the face of the standard is a ring piece J provided with a gas outlet K, the edge of the ring iece J fitting into the annular groove 1). v ithin the rin piece J there is mounted on the shaft G a disk 1 with a series of paddles H, acting as a fan, blower or booster. Following the ring piece J is a division plate L with a hole through the center. Following the division plate L is a tar extractor ring M fitted with a tar exhaust or outlet N, extending into a water seal. Within the tar extractor ring M is a disk 2 fitted to the shaft G and carryin a series of paddles or vanes I. The ringivl is followed by a division disk L and then by a water service ring which is sup plied with water from the pipe 3.

The water service ring 0 is followed by a division disk L and then by another tar extractor ring M. Two such tar extractor units are shown but one or any convenient number may be provided.

After the final tar extractor ring there is fitted an end plate P in the center of which Specification of Letters Patent.

is an inlet for the gas. A pipe 5 passes throu h the plate P to admit water to the ring The 'end plate P is further fitted with four bolt bosses 6 corresponding to the bosses B parts are in position bolts are passed through the bosses and the various rings and div sion disks are thus securely fastened in position. The various disks and their paddles mounted on the shaft G are held on the proper positionsby suitable distance pieces and the whole secured in position by means of the nuts and screw provided on the end of the shaft G.

Having described extractors I will now describe the working thereof.

The end plate P is coupled, by means of pipes to the gas producer and the gas enters thereby, where it meets with the water dripping from the pipe 5 after which it is immediately expelled to the periphery of the tar extractor ring by the paddles I revolving at great speed. The gas then passes back to the center of the extractoragainst the centrifugal force of'the paddles-on the other side of the paddle disk. After being washed by water which, drips from pipe 3 the gas passes'through the second stage of the tar extractor into the booster ring J which forces it to the engine or other consuming device.

The gasis ejected from the booster ring under pressure which varies according to the size of the disks and paddles and their velocity.

What I claim as myinvention and desire to secure by Letters Patent is on the base plate A. When all the construction of tar.

gas cleaning apparatus comprising alternate rings and plates interlocking one with the other and forming compartments, end plates one of which serves as a closure while the other is formed with a central gas inlet, bolts passed through saidend plates from one to the other and clamping together the assembled rings and plates, a horizontal shaft supported in the one end plate, and paddles mounted on said shaft and rotatable in said compartments and including imperforate plate portions alternating with said first plates to provide a sinuous passage through the apparatus and about the paddies.

2. A gas cleaning apparatus comprising front and rear standards, the former of rear standard and supporting one end of said shaft, alternate rings and plates interlock- 5 ing one with the other and forming circular gas chambers around said shaft, paddles mountedupon said shaft and Working in said chambers and alternating Withsaid plates to provide a sinuous passage p wn plates fr together through the apand bolts passing through said end 10 om' one to the other and clamping the assembled rings and plates.
